Mode of action
4-CPA can be absorbed by plant root, stem, leaf, flower, fruit. The biological activity duration is long.
Its main functions are as follow:
To form seedless fruits.
To promote fruit set and fruit enlargement;
Applications
As plant growth regulator, it can be absorbed by plant via root, stem, leaf, bloom
and fruit.
1. 4-Chlorophenoxyacetic acid ( 4-CPA ) is used to prevent abscission of bloom and fruit, inhibit rooting of beans,Single use: 10-30 mg/L, spray flower or deal with fruit, promote fruit setting.
promote fruit set, induce formation of seedless fruit, through flower spraying.
2. 4-Chlorophenoxyacetic acid ( 4-CPA ) can be used for ripening and fruit thinning.
3. 4-Chlorophenoxyacetic acid ( 4-CPA ) also has herbicidal effect at high dosageApplication
4. 4-Chlorophenoxyacetic acid ( 4-CPA )performs better when used in combination with 0.1% monopotassium phosphate.
